#Tutorial inversi res2dinv Pc
The inversion of a data set with 198 electrode positions (BLOCKS_22x9-ws.dat example data file) just takes about 17 seconds on a PC with a hex-core i7 CPU. On a modern multi-core Windows-based microcomputer, the data inversion takes from less than a minute for small surveys with 100 electrodes in a flat area to several hours for extremely large surveys with 6000 electrodes in rugged terrain. However, the parameters which affect the inversion process can be modified by the user. The program will automatically choose the optimum inversion parameters for a particular data set. Topographic effects can be modeled by using a distorted finite-element grid such that the surface of the grid matches the topography. It supports parallel calculations that significantly reduces the inversion time. A Pentium 4 (or compatible CPU) based microcomputer with at least 512 megabytes RAM and an 80-gigabyte hard-disk is recommended. Like RES2DINV, it is completely automatic and the user does not even have to supply a starting model. The RES3DINV program uses the smoothness-constrained least-squares inversion technique to produce a 3D model of the subsurface from the apparent resistivity data alone. The arrays supported include the pole-pole, pole-dipole, inline dipole-dipole, equatorial dipole-dipole, and Wenner-Schlumberger. This program is designed to invert data collected with a rectangular grid of electrodes. In areas with complex structures, there is no substitute for a fully 3D survey. The main limitation of such surveys is probably the assumption of a 2D structure. In areas where the geological structures are approximately two-dimensional (2D), conventional 2D electrical imaging surveys have been successfully used.
